Abstract

The invention belongs to the technical field of rubber detection, and particularly relates to a pressure pulse test hydraulic pressure system for rubber hose test. The system is characterized by comprising a fuel tank, a hydraulic pressure pulse generating device and a fuel feeding device. A fuel supply port and a fuel return port of the fuel tank are respectively connected with a fuel supply device and a fuel return port the hydraulic pulse generating device; a fuel feeding tube inlet of the fuel feeding device is connected to the fuel supply port of the fuel tank; the hydraulic pressure pulse generating device is directly connected with a test piece; and the fuel feeding tube outlet of the fuel feeding device is connected to the test piece. The invention has the beneficial effects of further improvement of the performance and stability of high-voltage pulse, more accurate test results, improved safety of rubber hose, and simplified system structure, and has important significance to the technical development of domestic hydraulic pressure pulse test bench.

Description

technical field [0001] The invention belongs to the technical field of rubber detection, in particular to a pressure pulse test hydraulic system for rubber hose detection. Background technique [0002] With the rapid development of my country's automobile industry, people's requirements for the safety of automobiles, especially the prevention of accidents, are becoming more and more stringent. As one of the active safety components of automobiles, the quality of automobile hydraulic brake hoses that transmit braking power is becoming more and more important. . Brake hose is a flexible conveying conduit mainly used in the brake system to transmit and store the hydraulic or pneumatic pressure for the vehicle brake, so its quality will directly affect the safety and reliability of the vehicle. sex. [0003] When the hydraulic system is working, due to the switch of the hydraulic valve, the start and stop of the hydraulic pump, and the change of the load, there will be serious ...
